Note
builHG > Only needed if not usign back substitution (very slow)
ldpcTxSystem > Contain the message passing decoder matlab implementation (very slow)
Contain a message passing decoder C implementation [mexdecoder.c] (faster but not optimal)
ldpcTxSystemFast> Contain a message passing decoder C implementation [mexfastdecoder.c] (fastest, but break the compatibility with the previous matlab code)
ldpcTest > Test for ldpcTxSystem
ldpcTestFast > Test for ldpcTxSystemFast
Not really useful file (SHOULD BE CONSIDERED DEPRECATED):
buildHG
ldpcTxSystem
ldpcTest
mexdecoder.c
## MATLAB R2016
From this version of MATLAB (maybe also others before), MATLAB tries to start a parallel pool automatically when a parfor keywork is reached, making the flag parallelComputation unuseful.
To disable this go to unchek Preferences > Parallel computating toolbox > Automaticallly create parallel pool.
## References
`doc/LDPC notes.pdf` are notes on the LDPC codes from the course I've attended at University of Padova.
`doc/presentazione.pdf` is a presentation on this project which contains very useful information for understanding the code.
